Application March 3, 1958, Serial No. 718,610

'6 Claims. (CI. 46-93) My invention relates to a toy boat and moreparticularly to a toy boat which will emit a fan-like spray or roostertail when the boat is towed or pulled while riding on the'surface of abody of water.

There is a need, around wading pools and the like, for fascinatingfloating toy boats to amuse the tots or small children and keep themoccupied and the satisfaction of such need is an object of my invention.

Another object of my invention is to provide a toy boat which will emita fan-like spray or rooster tail so that the children will continue tobe satisfied and thus provide a toy which will be used day after day.

Another object of my invention is to provide a toy which is inexpensiveto produce and which at the same time has such realistic action that thedevice is readily saleable, wanted by children, and readily used bychildren.

Other objects and advantages of my invention will become apparent as thedescription of the same proceeds and the invention will be bestunderstood from a consideration of the following detailed descriptionstaken in connection with the accompanying drawings forming a part of thespecification, with the understanding, however, that the invention isnot to be limited to the exact details of construction shown anddescribed since obvious modifications will occur to a person skilled inthis art.

Figure 1 is a view in side elevation and with parts broken away and insection of a device embodying my invention;

Fig. 2 is a sectional view taken substantially on broken line 22 of Fig.1;

Fig. 3 is a bottom plan view;

Fig. 4 is a perspective view of the conduit or water tube (shown inFigs. 1, 2 and 3) just after cutting;

Fig. 5 is a perspective view of the tube or conduit of Fig. 4 after thetrailing end portion thereof has been flared;

Fig. 6 is a perspective view of the tube of Fig. 5 after said flaredtrailing end portion has been flattened to provide a slot-like nozzle;and

Fig. 7 is a view similar to Fig. 4 of a modified form of conduit orwater tube; and

Fig. 8 is a perspective view of the tube shown in Fig. 7 after thetrailing end portion of said tube has been flattened to provide aslot-like nozzle.

Referring now to the drawings, the boat hull 10 is preferably providedwith a tail fin 12 so that in general appearance the hull and fin willresemble a modern hydroplane. On the bottom of the hull 10 is a groove14 which extends longitudinally of, and substantially centrally of, thebottom of the hull 10. This groove 14 is plugged by portions of thebottom of the hull or by extending the groove 14 the full length of thehull and then plugging it so that the groove 14 terminates short of thetrailing end portion of the hull 10.

A hole is drilled at an angle of substantially 45 to the plane of top ofthe groove 14and receives therein a conduit or water tube 16. Theforward end portion 18 is preferably cut at a 45 angle so that when thetube is installed as shown in Fig. 1, the said end portion 18 will benormal to the surface defining the upper wall of the groove 14. Theother end portion of tube 16 is preferably cut normal to the axis of thetube 16 to provide the trailing end portion 20. Preferably the saidtrailing end portion 20 of the tube 16 is flared to provide the flaredportion 22 illustrated in Fig. 5 of the drawings. Next said flaredportion 22 is flattened over a die or thickness gage so that thethickness of the slot 24, in the flared and flattened end portion 26,will have a dimension in thickness from about 0.010 to about 0.020".

When in operation a. suitable towing means is secured to the eyelet 28and the hull 10 is propelled by pulling or towing through suitablemeans, such as a long string and a long rod (not shown). Due to therelative motion between the water indicated by 30 and the bottom of thehull 10, water delivered to the groove 14 passes into conduit 16 and isemitted out the slot 24, functioning as a nozzle, and the pattern of thespray is a fan-like spray indicated by 32 in Fig. 1 of the drawings. Inview of the fact that the slot 24 when installed is in a vertical plane,the face of the fan-like spray lies substantially in a vertical plane.

As an alternate construction of a conduit means having an integralnozzle, I have shown in Figs. 7 and 8 a tube or conduit 34 which has aforward end portion 36 and the trailing end portion, as indicated inFig. 7, is normal to the axis of the tube 34 when cut. After cutting thetrailing end portion 38, a slot or kerf 40 is provided on a diameter ofthe tube 34 and alined with a diagonal from the lowest to the highestportion of the diagonal forming the forward end portion 36. Then a dieor thickness gage is employed and the trailing end portion 38 isflattened over said die to provide a slot 42 with kerfs 40 at the endportions thereof. The slot 42 functions similarly to the slot 24. Inaddition the kerfs 40 have the eifect of further spreading or increasingthe face area of the spray 32 over that provided by slot 24.

It is preferable to provide a fan-like spray with the lower portion ofthe spray contacting the wake 44, produced by the relative motion of thehull 10 and water 30. This is facilitated by the angle of the conduit 16and the pattern of the spray from a particular nozzle.

As an example, and not as a limitation, I have built a toy boatembodying my invention having an overall length of about 8 to 10 inches;the widest beam of the hull was 4 to 5 inches; the narrowest beam of thehull was approximately 2 to 2 /2 inches; the groove 24 had a height andbreadth of approximately 4 to 7 of an inch; the tube 16 had an OD.dimension of approximately of an inch; and the slot 24 had a thicknessof approximately 0.010 inch to about 0.020 inch and had a length ofapproximately M2 to A: of an inch.

Obviously changes may be made in the forms, dimensions and arrangementof the parts of my invention, the foregoing setting forth only preferredforms of embodiment of my invention.

I claim:

1. Toy boat comprising a boat body having a groove extendinglongitudinally of, and substantially centrally of, the bottom thereof;plug means terminating said groove short of the trailing end portion ofsaid boat body; and a conduit extending angularly upwardly andrearwardly with the forward end portion connecting with said groove andthe trailing end portion terminating in a nozzle for forming a fan-likespray with the face of the spray lying substantially in a verticalplane.
